HOSE-NOZZLE.

No. 871,256. Specification of of which the following is a specification.

'Myinvention relates to improvements in hose nozzles and particularly to a spraying device therefor, whereby may be simultaneously discharged a main stream and spray at an angle thereto.

The object of the invention is to provide an improved form of hose nozzle for fire fighting apparatus, adapted by the discharge of a fine spray around and at an angle to the main stream, to drive back the smoke and other products of combustion and form a protection for the operator.

A further object is to simplify the construction as well as the means and mode of operationof such devices whereby they will not only be cheapened in construction but willbe rendered more efficient in operation and unlikely to get out of repair.

A further object is to provide a simple form of adjustment for the spray device, whereby the said spray feature may be either dis ensed with and the nozzle used in the or inary manner, or it may be adjusted to deliver a greater or less amount at the will of the operator.

With the above primary and other incidental ob'ects in view, as will appear from the: spec" cation, the invention consists of theconstruction, the parts, the combination and arrangement thereof or their.

7 equivalents here-in-after described and set forth in the claims.

Referring to the drawings, Figure 1 is a view illustrating the nozzle and spray device in use, Fig. 2 is a side view of the nozzle partly broken away. Fig. 3 is a longitudinal sectional view of a portion of the nozzle.

Fi v4 is an exterior view of the discharge oflthe main nozzle member. Figs. 5 and 6 are views respectively of the main nozzle member and the deflector member.

Like parts are indicated by similar characters of reference in several views.

In constructing the device, in order to facilitate the manufacture and assemblin thereof, the main nozzle member is forme in three parts, a coupler section a, an intermediate section a and a tip section (1 screw threaded together. By the use or Patented Nov. 19, 1907.

non-use of the coupler section the device may be adapted to different styles of play pipes having connections of difl'erent diameters. The main nozzle member thus formed has a central bore a preferably somewhat tapering and a bell shaped or flaring discharge oriflce a as shown in Fig. 2.

VVrthin the interior of the tip section a and adjacent to the discharge orifice is formed a seat a upon which normally rests adeflector member I) when the nozzle is being used in ordinary manner.

The deflector member 1) consists of a ring having a flaring exterior b, a central bore slightly tapering in a direction the reverse of that of the main nozzle member. The inner side I) of the deflector member is formed conical to fit the seat a)". The central bore of the deflector member is of slightly less diameter than that of the main nozzle member thus forming a shoulder within the bore adapted to interrupt the flow of the Water forming the exterior surface of the stream.

When the deflector member is adjusted away from the seat a by means hereafter dethe stream, when interrupt d as before mentioned, will be deflected from the main stream and projected at an angle thereto in the form of a spray through the outlet passage intermediate the flaring exterior b of the deflector member I) and the bell shaped discharge orifice of the main nozzle member.

It is apparent that the spray is not deendent on the lateral pressure of the water ut is due to the direct impact force of the stream against the shoulder formed by the reduced opening in the deflector member and will be projected to a distance with considerable pressure.

To adjust the deflector member I) to and from the seat a fingers b are provided on the deflector member, projecting arallel with the axis of the nozzle. In the drawing four such fingers are shown, however a greater or less number may be employed. The exterior surfaces of said fingers b are arcs of a circle concentric with the axis of the nozzle bore. l/Vhen assembledin position the fingers 5 project into longitudinal o enings a formed in the tip section a he tip section a is formed with an enlarged head or band a at its extremity. The openings a extend through said head and are continued in the form of a groove a in the ternally screw threaded collar 0 located.

about the reduced portion of the tip section a and intermediate the bead or band a and i a similar bead or band 0 on the intermediate section a The arrangement is such that the beads a c while preventing any lateral movement of the collar 0 will permit a revoluble movement thereof. The beads a7- 0 extending above the collar 0 are ada ted to protect the latter from accidental b ows or knocks.

The engagement of the screw threaded fingers b with the collar 0 is such that a revoluble movement of said collar will cause the deflector member to be moved to and from the seat a A portion of the finger b adjacent to the extremity thereof, is left unthreaded as at b or said portion 1) may be in the form of a lug. When in use the portion 6 by engagement with the interior screw threads of the collar 0 will limit the outward movement of the deflector member I); the movement of the deflector in the opposite direction being limited by the seat a. It will be noted by reference to Figs. 2 and 3 that the collar 0 is screw threaded only throughout a portion of its width,to permit the deflector a limited movement beforethe portion engages the interior screw threads of the collar.

It is obvious fr;m the above description that there has thus been produced a hose nozzle which possesses the particular features of advantage enumerated as desirable, and

which is obviously susceptible of modification in its form, proportion, detail construction and arrangement of parts without departing from the principle involved or sacricing any of its advantages.

Having thus described my invention I claim;

1. In a hose nozzle, a main nozzle member, a deflector member capable of longitudinal movement only, located at the discharge end of said nozzle member and concentric therewith, having an opening of less diameter than that of the main nozzle member, said deflector member being offset in its relation to the nozzle member to form a passage intermediate said nozzle member and deflector member, having its general direction at an inclination to the axis of the nozzle bore, substantially as specified.

2. In a hose nozzle as described, a main nozzle member, a non-revoluble deflector member, having a central discharge orifice therein, a seat lIl said nozzle member upon which said deflector member is adapted to rest, means for adjusting said deflector member to and from said seat, substantially as specified.

3. In a hose nozzle as described, a main nozzle member, a non-revoluble, longitudinally adjustable deflector member having a flaring exterior, and a concentric opening therein, means for adjusting the deflector member to and from the nozzle member to regulatethe opening intermediate said parts, substantially as specified.

4. In a hose nozzle as described, a main nozzle member, having a central bore, a seat formed'in said bore, a deflector member located within the discharge end of said nozzle, having a flaring exterior and an openingconcentric with the central bore of the nozzle member; said deflector member adapted to normally rest upon said seat, and independent means to adjust said deflector memer longitudinally to and from said seat, subnozzle member, a deflector member, projecting fingers on said deflector member, screwthreads on the exterior surface of said fingers, an internally screw threaded collar engaging the screw threads of said projecting fingers, whereby said deflector member may be adjusted to and from said nozzle member,

substantially as specified.
